Public bug reported: I've had this issue since about 12.10 or whenever the oss modules with disable in the kernel.
i.e CONFIG_SND_MIXER_OSS CONFIG_SND_PCM_OSS CONFIG_SND_PCM_OSS_PLUGINS Ubuntu is one of the few distros to take out these module from their kernel builds. On Debian, Fedora, Arch and Opensuse the modules are in the kernel (you usually have to manually load them (i.e they are present by default wbut disabled - with ubuntu the modules are actually removed.) There is one game in particular I play, it in an old obscure game called paintball2 - http://digitalpaint.org/ It uses OSS by default - it does have an SDL option too (which works in ubuntu) - but the SDL plugin is buggy. With all other distros I can just manually load the OSS modules, with Ubuntu I have to recompile the kernel in order to have OSS sound. Could we not change the policy and include the modules (the size difference will be basically none.) so at least people have the option to use them without the hassle to recompiling the kernel - its a PITA having to do it again each time there is an update. I know of aoss and padsp - these tools do not work (at least with this game), they never have in multiple machines (all have had intel HDA cards) i.e ------------------------------------- aoss ./paintball2 LoadLibrary("./snd_oss.so") /dev/dsp: Invalid argument SNDDMA_Init: Could not mmap /dev/dsp. ------------------------------------- --> no sound ------------------------------------- padsp ./paintball2 Paintball 2 -- Version 2.0 execing configs/config.cfg Console initialized. ------- sound initialization ------- LoadLibrary("./snd_oss.so") SNDDMA_Init: Sorry, but your soundcard doesn't support trigger or mmap. (00005100) ------------------------------------- --> no sound. As soon as i recompile the kernel and add the modules it works fine. How can I get the modules re-added - there is no harm having them in the kernel but disabled on startup...
